Welcome to BYC. Glad you decided join our flock. Build your coop/run as big as you can afford to build it in case you decide you want to increase the size of your flock later on. Very few members are immune to "chicken math." ) Also, be sure and build it so it is predator proof using hardware cloth instead of chicken wire. There are too many predators (including dogs) that can tear through chicken wire, or squeeze through the openings in the mesh. Please feel free to ask any questions you may have. We are here to help in any way we can. Do you have a breed preference?
